Help reading files (.mbs, .mbp1) from KOA3

I'm wondering if there is a way to produce/collect reading times/stats from my KOA3. I see there are extra files with .mbs and .mbp1 extensions. When I view the .mbs file in a hexeditor I see a few mentions of 'timer' like timer.model, timer.average.calulator. And in the .mbp1 file I see like 'next.in.series' and 'annotation.cache'.

Does anyone have some code or specification of these files before I attempt to write my own?

Does anyone know if reading stats exist? Such that I could suck them out when the kindle is connected to PC?
